Who Is the Real Enemy of the Palestinian Arabs?

I have just a few questions:

1. If the Palestinian Arabs are so badly-off, how come their leaders wear such good clothes and look so well fed?

2. How come they still revere Arafat? How good a leader was he if he brought them to such dire straits? In 20 years, couldn't he have brought them out of poverty, lousy schools, sewage in the streets, massive unemployment? While he, Arafat accumulated a personal fortune of 900,000,000 US Dollars.
